LOCK-BUCKLE FRAME.

SPECIFICATION forming part of Letters Patent No. 695,405, dated March 1, 1902.

Application filed May 9, 1900. Serial No. 16,083. (No modelJ To all whom it may concern:

Be it known that I, MATTHEW W. LYNCH, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented a new and useful Lock-Buckle Frame, of which the following is a specification.

My invention relates to improvements in lock-buckle frames which are so constructed that the buckle-tongue is pivoted above the strap to be secured and in which the said tongue when in a locked position passes downward through the strap and into a recess in the body or casting, the present invention being designed as an improvement upon the construction shown in my Patent No. 573,093, dated December 15, 1896, having for its objects, among others, to reduce the weight, lessen the cost of manufacture, and to provide a better and neater-looking buckle when attached to a strap.

The novelty resides in the peculiarities of construction and the combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and'then particularly pointed out in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a side elevation with the strap in section and a portion of the buckle-frame brokenjaway and parts in section with the tongue in its locked position. Fig. 2 is aplan with the tongue'in the recess, the strap not beingshown. Fig. 3is arear View of the frame with thelugs in section and the tongue thrown up out of the recess. Fig. 4 is a'front view of the staple before being riveted to the frame, the tongue being removed.

Similar letters refer to similar part throughout the several views.

The frame a is acasting of metal the sides of which are parallel through the central portion and rounded on the two front corners and has rounded lugs f projecting from each side on the rear corners. (See Fig. 2.) In thickness the frame is about equal from the rear (marked 00) to about two-thirds the distance forward. Then it is reduced from the top to allow the strap to be attached in the same manner as described in the patent granted to me December 15, 1896, No. 573,093. The mortise Fig. 1, is cored through the frame from side to side and is drifted smooth to receive a lock-bolt i, which .is fastened, in both locked and unlocked positions and made and operated the same as described in said Patent No. 573,093.

The staple b, Fig. 4, is reduced in diameter at the center, forming abearing for the tongue 0, and is also reduced at the two downwardlyprojecting ends, forming tenons which are inserted into holes drilled through the lugs f on the frame a and headed to the same, as shown clearly in Figs. 1 and 3. The tongue 0 is a piece of rod of the proper size and length bent around the staple at one end and fitted to the hearing, as shown in Figs. 1, 2, and 3.

It will be seen by reference to the drawings that the construction shown is much easier and cheaper to manufacture than the frame described in my former patent, and for equal strength is of'one-third lessweight.

It is also clear that the staple at its two upper corners or curves has greater strength than the arrangement for supporting the tongue, as shown insaid former patent.

When the tongue is in the position seen'in Fig. 2, with its lower end extending into the recess h in the top of the casting, which re cess intersects the mortise g, and the flat bolt vlmoved into the locked position, the latter prevents the tongue from being moved on its pivot, so as to be swung out of the recess; but when the bolt is moved endwise in the mortise g, so that the notch in the bolt (seen in Fig. 2) comes coincident with the said recess and the end of the tongue, the latter may be swung up into the position seen in Fig. 3.

Having thus described my invention, what I claim as new, and wishto secure by Letters Patent, is I In a lock-buckle frame, the combination with the body a having lugs f and transverse mortise g for the bolt, and a recess in its face communicating with the said mortise, of a staple having tenons passed through said lugs and secured to the under face of the said body in recesses therein, a, tongue pivoted on the I name to this specification in the presence of cross portion of said staple, and a flat bolt two subscribing witnesses.

mounted to move endwise in said mortise and w 1 to intersect said recess when in its locked po- MArlrlHEv W LYNCH sition and prevent removal of the said tongue, I Vitnesses: substantially as shown and described. PATRICK LYNCH,

In testimony whereof I have signed my M. E. LYNCH.
